Abstract
Several rust-transforming reagents based on phosphating technology were studied. The reagents respectively contained potassium ferrocyanide, aromatic oximes (SO) or amide material (GA). By dripping CuSO4 test, linear polarization and polarization curves test, the anti-corrotion performance of phosphate coating were characterized. The results showed that: GA and SO could improve the anti-corrosion performance of phosphate coating. SO restrained the dissolution of metal relying on strong chelation, and the restrained effect of GA depended on durative oxidation and chelation. Comparing to SO, GA could enhance the density of phosphating coating significantly. In addition, the chelation of potassium ferrocyanide had little effect with the anti-corrosion performance.
